The Claim
Long-term multivitamin supplementation has no modification of its cognitive benefits by common risk factors for cognitive decline, including age, smoking, alcohol use, body mass index, diabetes, hypertension, cholesterol levels, folate intake, fruit and vegetable consumption, or depression history, in men aged 65 and older.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In men aged 65 and older, taking multivitamins long-term provides the same cognitive benefits regardless of whether they have risk factors like high blood pressure, diabetes, smoking, or depression.
See the scientific wording
The cognitive benefits of long-term multivitamin supplementation are not modified by common risk factors for cognitive decline such as age, smoking, alcohol use, body mass index, diabetes, hypertension, cholesterol levels, folate intake, fruit and vegetable consumption, or depression history in men aged 65 and older.
Taking multivitamins every day for many years does not change how the brain ages or how memory and thinking skills decline in older men, no matter what other health conditions they have or what they eat.
What the research says
1 studyStudy: Long-Term Multivitamin Supplementation and Cognitive Function in Men
This big study gave older men either a multivitamin or a sugar pill every day for 12 years and found their memory and thinking skills got worse at the same rate no matter which group they were in. So, having high blood pressure, diabetes, or eating poorly didn’t make the multivitamin help more or less — it didn’t help anyone.
